What do you mean? There are no "factions" as per MTW, there are instead a bunch of playable kingdoms (and one Empire), armies of duchies and a horde of counts. And you play a dynasty rather then a country or faction. It has a complete fuedal system. That is that a king has some dukes (and maybe some counts) that are their vassals, and every duke normally has a couple of counts as their vassals. You get some £$€ from you vassals and if they are loyal enough you can use their troops. Though only christians are playable
